TO WHOM IT MAY CONCERN:

' Bfeit-known that I, EDMUND BENNETT, of 'Nankin, in the county of Wayne, and State of Michigan, have invented chew and useful Improvement in Potato-Diggers; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and'to the letters of reference marked thereon, and making a part of this specification. V

Figure 1 is a side view of my invention. I Figure 2 is an opposite side view of the same.' Figure 3 is a vertical sectional view .of the same. Figure 4 is a view of the slotted-scoop. The nature of my invention consists in so constructing an apparatus for digging potatoes, that it will effectually separate the vines from the potatoes, and thoroughly clean the potatoes, and deliver them, ready for loading, at the rear of the apparatus.

Similar letters indicate like parts in each figure. 1 In manufacturing my apparatus, I firstrmake a suitable frame and box, wheels, B. Upon the inner side of the wheel B, in fig. 1, I attach a drivin sectional view, fig. 3,) which meshes upon one sideinto the pinion E, which F upon the shaft. Upon the opposite side, this same cog-wheel meshes into the pinion H, upon the shaft I. To the front of the frame and box A, I attach a slatted scoop, J, set at the proper angle to readily pass under the hill of potatoesto be dug. The entire hill, tops and potatoes, are taken'up by this slatted scoop, and, as the apparatus is drawn forward, are forced up until they reach the curved teeth upon the endless chainK, which is while the potatoes drop under other curved teeth in theendless belt L, which is carried by the shaft I. These curved teeth in-the endless belt L force the potafoes back upon the shaker M, which should be constructed of wire, and through the openings of which the dirt is allowed to fall, while the potatoes aredelivered at the rear of the machine. N is a-shield to raise the teeth less belt L. O is another cogwheel, placed upon the opposite end of the shaft G, and meshes into the pinion P, and operates the lever Q, and gives motion to the shaker M. R is a lever, to which is attached the cord or chain S, which passes over the fulcrum T, by means of which the driver can raise or lower, the front of the apparat us as he may 'desire. U is an adjustable seat, working upon the reds V. W is an adjustable attachment, to which to fasten the shafts or tongue for the horses. X are small wheels,

which are designed to run in the dead furrows, to sustain the front of the apparatus.

What I claim as my invention, and desire to secure by Letters Patent, is- 1. The method of separating the vines from the potatoes, endless belt L, and shield N, arranged substantially as described and forthe purposaspecified.

2. The combination of theabove with the frame or,.box A, the wh O, the pinions E, H, and P, the shafts G and I, the shaker M, the w the cord or chain S, and the fulcrum T, when constructed substantial A, hung upon proper axles, Chanel g cog-wheel, D, (also shown in the pinion givesmotion to the cog-wheel heels X, the slatted scoop J, the lever B, ly as and for the purpose described.
